ABSTRACT:
A spring hinge between a bow cheek and a bow of a pair of spectacles is described, having two hinge parts (3, 4), each associated with one of these spectacle parts (1, 2), one of which forms a bearing fork (6) having a hinge axis (5) for receiving the other hinge part (3), which is guided so it is displaceable with the aid of a sliding part (7) in a housing (9), and having a coiled spring (13) situated between two legs (12) of the sliding part (7), which is supported on one side on a web (14) of the sliding part (7) connecting the two legs (12) and on the other side on a housing-fixed buttress. In order to achieve simple installation conditions, it is proposed that the housing (9) has a closure part, which forms a receptacle opening (8) of the associated spectacle part (1) for the sliding part (7), and which forms the buttress for the coiled spring (13).
